Abstract

A stirring mill, including a horizontally arranged milling vessel and a stirring shaft which is arranged therein so that it can be rotationally driven are provided. The stirring shaft has a first stirring shaft section adjacent to an inlet for material to be ground, which has a smaller diameter D24, and a second stirring shaft section adjacent to an outlet for material to be ground, which has a larger diameter D25 and in which a separating device is formed. Bypass channels leading into the separating device are formed in the first stirring shaft section.
